, v 1 My invention relates to a pouring stopper for bottles. It has todo, more particularly, with a stopper adapted to be applied to the neckof a liquid-containing bottle, the stopper being provided with a pouringspout to facilitate pouring of the liquid from the bottle.

Oneoi the objects of my invention is to provide a bottle stopper andpouring spout which is of such a structure that the liquid can be pouredfrom the bottle with ease and in a smoothly flowing uniform stream.

Another object of my invention is to provide a pouring stopper for abottle which can'be applied to the neck of the bottle with ease and beremoved therefrom when necessary with little difficulty but which isordinarily effectively maintained in position without danger ofaccidental displacement from the neck.

Another object of my invention is to provide a stopper of the typeindicated which can be applied to necks of botles varying somewhat indiameter or contour.

Another object of my invention is to provide a stopper of the typeindicated composed of a minimum number of parts, the separate partsbeing so designed that they can be manufactured in large quantities atlow cost, the parts bein of such a nature that they may be assembledeasily and retained in assembled condition.

Another object of m invention is to provide a stopper of the typeindicated which is of a sanitary nature and can be cleansed with ease.

The preferred embodiment of my invention is illustrated in theaccompanying drawing wherein similar characters of reference designatecorresponding parts and wherein:

Figure 1 is a vertical sectional view taken through a pouring spout madeaccordin to my invention,

Figure 2 is a perspective view partly broken away.

Figure 3 is a horizontal section taken on line 3-3 of Figure 1. v

Figure '4 is a vertical sectional view taken through the pouring spoutand the neck of the bottle to which it is applied, showing liquid beingpoured from the bottle.

With reference to the drawing, I have illustratedmy pouring spout ascomprising a shell I formed of metal, a spout 2 also iormed of metal,and a liner or bottle neck gripping collar 3 which is preferably made ofrubber. 1 The members I and 2 are preferably made of thin metal whichwill not corrode, such as stainless steel, aluminum, et cetera. However,it is also possible to make 3 Claims. (01; 215 -79) these members ofplastic or other non-corrosive materials. The material of the member 3is preferably compressible rubber although it may be any other suitablesanitary compressible or elastic material.

a The shell I is of inverted dome-like form. The lower portion curvesinwardly forming a depending annular skirt 4 which receives and closelysurrounds the compressible rubber member 3. A shoulder 5 on the upperend of the member 3 limits the inward movement of the member 3 into themember I and an inturned lip B on the lower edge of the skirt 4 preventsthe withdrawal of the member 3. The upper portion 1 of the member I isof reduced diameter due to the inward curving thereof and thus providesan air chamber 8 in the upper end of the member I above the top of themember 3.

It will be noted that the member 3 is of inverted frusto-conical form sothat it snugly fits within the skirt 4. The side wall 9 of the member 3is adapted to receive and grip the neck of the bottle as shown in Figure4. The lip of the neck of the bottle will engage and seat on the lowersurface of the top wall II) of the member 3. This top wall II] isprovided with an opening I I through which is drawn and securely held inposition a small vent tube Ila. The purpose of the vent tube Ila is toprovide an inlet for the air into the bottle, the air passing from thechamber 8. Air enters the chamber 8 through an inlet I2 provided in themetal wall portion 1 of the member I.

The pouring spout 2 fits within an opening in the top of the wall I ofthe member I and is held in place by a helical retaining spring I3'whichsurrounds the upstanding portion Illa of the upper wall I I]. Thisprevents movement of the pouring spout axially through the opening. Thepouring spout has a lower end portion I 4 which extends into the shell Iand fits snugly in an upstanding socket portion I6 formed integrally onthe top wall Illa of the member 3. The outer end of the pouring spout isprovided with a hinged flap valve IBa which will open automatically whenthe stopper is tilted with the bottle.

The members I, 2 and 3 can be made separately and then be assembled withease, In assembling these members, the spout 2 is first mounted on themember I, then the member 3 is inserted in the member I, the lower partI4 of the spout being guided into the socket I6 of member 3 and held inplace by the retaining spring I3.

In using this device, it is positioned on the neck of the bottle asshown in Figure 3. The material of the member 3 will be compressedsufiiciently to compensate for any irregularities in the bottle neck andwill frictionally engage the neck to prevent accidental displacementtherefrom. Air will be permitted to enter to bottle and take the placeof the displaced liquid, through the inlet l2 and the vent tube I la. Itwill be noted that the opening I2 is disposed above the top of the upperwall [0 of the member 3 and is spaced laterally opposite opening I Iwhich is adj acent the socket l6.

It will be apparent from the above description that I have provided apouring spout for bottles having a number of advantages. Some of theseadvantages have been mentioned and others will 7 be apparent.

1. A pouring spout adapted to be applied tothe neck of a bottlecomprising an inverted cup-like shell, an inverted cup-like liner memberdisposed within fthe sh'ell, a socket formed by the lower end of theliner member, a pouring spout carried by the shell, said spout having aportion extending within the shell and fitting within the socket por-'tion formed by the liner member.

2. A pouring spout adapted to be applied to the neck of a bottlecomprising an inverted cup-like shell, an inverted cup-like liner memberdisposed. within the shell and forming a socket for receivingthe bottleneck, said liner member being formed of compressible material and havinga top portion, a skirt portion, and an upstanding socket portion formedon said top portion, the top of the liner member being spaced from theupper inner part of the shell to provide an air chamber therebetween, anair inlet in the shell leading into said chamber, an air inlet in theliner member leading from said chamber to the socket in the linermember, a pouring spout carried by the upper inner part of the shell andhaving a portion extending downwardly into the shell, said portionfitting into an upstanding socket portion carried by the top portion ofsaid liner member and communicating with the interior thereof.

-3, A pouring spout according to claim 2 wherein the inlet opening inthe shell is spaced above the to of the liner member and is spacedlaterally from said spout.
